Overview

The vision for mobility using a “highway loop” around Houston dates back to the early 1960s. 

 

More than 50 years later, this vision is becoming a reality with the design and construction of the remaining segments of SH 99 Grand Parkway, Segments H, I-1 & I-2. At 180+ miles, this circumferential scenic highway will be the longest highway loop in the United States, traversing seven counties and encircling the Greater Houston region, which is the fourth-most populous city in the United States.

In March 2017, the Texas Department of Transportation awarded the $855 million design-build construction contract for Segments H, I-1 & I-2 to Grand Parkway Infrastructure, a joint venture led by global infrastructure leader Ferrovial Agroman, along with Webber LLC and Granite Construction Inc.

Construction along the corridor, stretching from the US 59/IH 69 interchange to the north and SH 146 in Baytown to the south, commenced in 2018. Construction activities are currently underway, including bridge construction, roadway paving, right-of-way acquisition with property owners, and utility relocations.

Fast Facts:

 

  • Segments H, I-1 & I-2 represent 52.8 miles of the 184 mile SH 99/Grand Parkway loop

  • Acquisition of easements through 375+ land parcels

  • 80 new or substantially reconstructed bridges will be built

  • The first segment – Segment D – of SH 99/Grand Parkway opened in August 1994; the most recent segment – Segment G – opened in March 2016
